PROTECTIVE COVERING FOR VEHICLE TIRES.

Application filed July 19,

My invention has for its object the providing of an ellicient7 yet simple metallic protective covering for `the tires of vehicle wheels, especially the.. wheels of automobiles; thereby to eliminate punt-tures, also to reduce blow-outs and the wear on the tire; at the saine time not interfering with ,the normal resiliency of the tire.

My invention furthermore has for its object so to construct and mount the protective covering of the tire on the latter and the wheel rim that when the tire is deflated, the protective covering will support the weight of the vehicle, and thus prevent injury to f the tire.

A further object of my invention is so to construct my protective covering that it may be conveniently assembled on the wheel rim about the tire.

Other features of my invention, its details of construction and application are hereinafter fully described with reference to the accompanying drawings.

In the drawings Fig. 1 is a. side elevation of an. automobile Wheel and tire with my protective covering mounted over the tire and secured to the telly of the wheel, and shows a portion ot the supplementary rim broken away disclosing one of the radially disposed bolts by which my covering is held closely to the tire, and I similarly show -in a sect-ion of the armor broken away the male and female joints of the two sections of my protective cover;

F ig. 2 is a side elevation of a fragment of a tire and wheel and shows a central longitudinal section of my protective covering in place over the tire and the rubber tread I provide on the periphery of the said covering Fig. Qa is a. perspective View of a fragment of the clamping means by which my protective covering is fixed to the felly of the wheel;

Fig. 7 is a section taken on the line indicated by the arrow 7 of Fig. 3, showing the slot provided the outturned flange on the inner periphery of my protective cover and .illustrating the means by which the lateral movement `is provided for 'the radially disposed bolts which fasten the cover to the supplementary rim; and

Fig. 8 is a fragmentary section of the supplementary rim and outturned flange on the inner periphery of the protective cover, showing more ,clearly certain details of construction. f f

Referring now to Fig. 1 the auxiliary protective covering n. is mounted over the tire b and comprises two sections c and Z which are held in place by the inturnedchannel-like extensions of the supplementary rims c and f which are fastenedto vthefelly g of the wheel by transverse bolts 7L, as more clearly seen in Fig. 3.

The protective covering a is provided with outturned flanges z' and on each side of its inner periphery, and in which are a number of slots 12 and 13, respectively. A number of bolts 'm and n are 'disposed about the supplementary rims in housings as at 79, in which openings 15 are provided in the lower portion of the channnel-like extension, and corresponding slots 16 `in the upper side of the said extension. The vbolts m and 1L are provided with nuts m and n. withv extended flangesand with washers.

These bolts serve to hold the protective covering securely to the supplementary rims e and f, and are provided with comple` mentary coil springs 2 and 3 and 4l and 5 seated over the bolts, one on each side of the flanges z' and y' rand bearing against the upper portions of the rims c and f and the nuts m and n. and the washers7 thus holding my protective armor securely to the tire. i

The usual rim clamps 6 are provided for mounting the tire to the wheel as shown in Fig. 5.

The two sections of my protective cover* ing c and Z are provided with male and femalejoints 10 and 11 which permit the two sections to be slightly adjustable to loo j the change. in eirenmlerenee of the tire. and a liner 1S is provided between the supplementary rims c and f and the shoulders ot my ln'oteet'ive eovering to provide a dust proof' eonneetion.

The radially disposed bolts y/11y and n are subjeet to a slight lateral movement when the tire. is dellated and the two seetions ol the armor are tort-ed eloser tosfether. and this lateral movement is provided for by the slots l2 and 13 in the ontturned tlane'es i'. and j being made large enough to aerommodate this movement of the bolts.

A. rubber tread Qt) is fixed on the outer periphery ot my proteetive eover to provide better traetion on the road surliaee.

The assembly of my proteetive eoverim:l over the tire is as follows.

The tire is mounted on the wheel .u in the usual manner. but is deflated and my protective armor is plaeed over the. tire. one seetion atI a time and closely titled tol'ether at the joints 1t) and tl. The wheel is laid on its side and the springs 2 are placed adjacent to the slots l2 in the llange i and the supplementary rim e is plaeed over the onttnrmfd [lange f'. the springs` 2 are plaeed over the bolts m and. the said bolts are inserted through the onenine ttl in the supplementary rim c and through the springs f2.. and the nuts fm are then threaded onto the said bolts m. The rim f is then assembled about the other side ot the Wheel. and both the supplementary rimsc and 7"' are bolt'ed onto the telly of the wheel b v the transverse bolts and my protective Cover is mounted over the tire and ready to be used.

The radial adjustment ot my proteetive eover as before mentioned is provided for by the play allowed between the bolts m and a. in the slots 12 and 13. respectively.

lVhen a tire is inflated the joints l0 and 1 1 between the two seetions ot my eover will not be completely closed. but in ease the air should escape from the tire, the sections c and al will be forced together by the springs il and 5. and the weizrh( ol' the automobile thus forming; a rigid and inflexible Lfuard thereby 1nal in r it possible lo drive an automobile equipped with mj.' proteetive eovering for pneumatie tires when tlnI enelosed tire is dellated without damage lo the tire or the ensonumv ioltinjay ot the ear.

The seetions of In'v protet'tive eovelilig are held snugly around the iullated tire by the tension ot' the springs on the radially disposed bolts. thereby preventingr any independent movements on the rims. and providing` a praetieal and useful eovering l'or tires. whieh will eliminate all possibility` ot tire trouble trom airvthine'. but the old age ot the tire.
